ROTARY DINING-TABLE.

SPECIFICATION forming part of Letters Patent No. 396,089, dated January15, i889. Application filed July 80, 1888. Serial No. 281,474. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, DANIEL JOHNSON, a citizen of the United States,residing at Kansas City, in the county of Jackson, State of Missouri,have invented certain new and useful Improvements in RotaryDining-Tables; and I do hereby declarethat the following is a full,clear, and exact description of the invention, which will enable othersto make and use the same, reference being had to the accompanyingdrawings, forming a part of this specification.

My invention has for its object, primarily, a combined rotary table andadjustable chair adapted for saloons of sea-going vessels and of otherdescriptions, in which the occupants of the chairs may be served inrotation from one stationary base of supply without the danger andinconvenience incident to the person making the circuit of the tablewhen the vessel is upon the seas, and also enabling the persons seatedat the table to be served with dispatch; and it consists in the novelconstruction and combination of parts hereinafter fully described,andspecifically pointed out in the claims.

In the drawings, Figure 1 is a view in perspective of a circularrotating table supported upon a central rotating shaft extending throughthe floor, and chairs adjustably attached to and suspended from thetable. Fig. 2 is a view in perspective of the table and chairs, takenfrom a position looking up from beneath the table and showing thesupporting guides for th e chair supports. Fig. is a detail verticalsectional view taken llll'Ollgll the table and floor, showing therotating power-shaft bearing and pulleys. Fig. 4 is a detail view of oneof the retaining-guides and a portion of the chairsupports therein. Fig.5 is a transverse sectional view of the guide and the portion of thesupport as seen in -l-. Fig. 6 is an alternate form of chair.

Similar letters of reference iiulicate corresponding parts in all of thefigures.

A represents the floor of a dining-saloon. (z a are the supporting-beamsupon which the floor is laid. a is the ceiling on the under side ofbeams a a. Through the floor A, between the beams a a, is first made ina vertical relation a cylindrical shaft-opening, a

and through the ceiling a, ma Vertical line with the opening a is made asimilar opening, (6*. Upon the under side of the floor A is placed ajournal bearing or box, I), which has an opening, I), the proper size toadmita power-shaft in a vertical relation with the opening a in thefloor A, with which it registers, and at opposite ends is provided withears 5 19 which are perforated in a vertical relation at Z2 b Aduplicate journal bearing or box, b", is then made, of a similar size tothe bearing Z), which is placed upon the top portion of floor A, withits opening I) in a vertical line with the opening I) in the bearing 5.Through the ears b of the bearing 19 are made the perforations o whichare in a vertical line with the perforations Z1 of hearing 5 Properopenings are made in the floor A in line with the perforations 1) b andthrough said perforations in the cars Z1 Z1 and the opening in the floorare inserted the screwbolts 6 6 which are provided with the nuts 11 band secure the opposite bearings together. A cylindrical shaft, B, isthen made of the proper length to extend in a vertical relation at oneend above the floor A the desired height of the table and the lower endfitted to and extended through the openings or bearings if b of thejournal-box 1) b and through the ceiling a a suitable distance, and uponthe extreme end of said shaft B is placed a horizontal loose pulley, band upon said shaft B, in close relation to and above said pulley 1) isfixed rigidly on said shaft a horizontal pulley, 12. Around the pulleyZ1 is placed a band, Z9 which is connected with the engine. A suitabledistance away from the shaft B, directly over the band 11 an opening,a", is made through the floor A, and a similar opening, a in a verticalline with the opening a, is made through the ceiling a, through whichopening is inserted a bar, 0, which extends below the band 11 upon thelower end of which bar is placed the bandshifting rods 0 0'. Upon theupper portions of floor A, near the opening (0*, is placed a stationarylug, 0 upon which is fulcrumed a lever, C. To one end of the lever C,which extends to a point over the opening a in the floor, is pivoted theupper end of the bar 0, the opposite end having a foot-plate, 0

For the purpose of supporting and staying shaft B-in its verticalposition braces D D D D are made, which are attached at their lower endsrigidly to the door A on opposite sides and a suitable distance awayl'rom said shaft 5 l3 and extended in an upwardly-inclined direction tothe sideot' said shaft 1 Around shaft B is placed loosely acollar, (,7,to which the upper ends of The braces l) l) are rigidly attached. Uponshaft 13 and above the collar To (Z is cast, or otherwise rigidlyattached, a circular flange, T1 of the cmnparative size of the collar(1, upon which collar the flange I) atiorded a bearing and turns in.union with the shaft l3. Upon The upper end of the shaft 15 B, attachedrigidly thereto in a ln'n'izontal relation, is a circular flat plate,1). Upon the plate I), and attachtsl tixedly thereto in a htn'izontalrelation, is placed a circular llat table, E, the attachment to theplate I) of said Table being made at a central point from the outeredge, (4*, of said table E. Extending radially from the plat e o to theouter edge of the table It are placed The htn'izontal suppmTing-bars cc, and extending radially from the flange 11 in the same vertical planeof bar e c, in. an. upward direction, to and (.OllllOCTOtl with theextreme ends of the bars e, are the brace-bars c (2, between. which barse e are placed suitable trussed portions, c (4 llpon The under sideportion of the table E, between The contiguous radial supportingbars 0c, and extending in The direction of The plate I) in a parallel relationto each other, and also at an angle To a line drawn radially from thecenter of the table and arranged. a suitable distance apart, are rigidlyattz'iched the slotted retaining guide-plates F. The plates F are madefrom suitable longitudinal l'latpieces of metal, narrow in width, and.ex- 40 Tending in the longitudinal direction of, and in the under sideportion of, said plates are made the dovetail grooves f f, of a suitabledepth. The outer edge portions of the plates which form the sides f f ofthe grooves are thus ln'ought closer in relation than at the bottom ofthe groove. A series of adjustable suspended chairs, (l (l, are thenmade to slide to and from the table A, and for this purpose variousnmditications may be devised, The constructitm, as shown in thedrawings, illus- Trating a highdiack chair. A folding-back chair may beused and pushed entirely beneath the table, if preferred.

'Forthe purpose of suspending the chair :nljustably from the table, twovertical. sup ports or rods, g g, are made, each oneof which is providedat its upper end wit h a forked p0]? tion, g g To the upperends of theportions g g is attached rigidly in a horizontal relation a bar, g",which is made shorter inlength than the plate 1 and in a wedge shape,adapted To fit; The dovetail groove f and slide Therein. The lower endsof supports 9 g extend in a downward direction to within a suitabledistance from the :tloor A, and To said ends at right angles, or in ahorizontal relation in a (,lirection opposite to shaft ll, are

firmly attached short parallel rods g g hwhieh exten d a 'sullieientdistance to :form a :t'oot-rest, From the outer ends of the rods g" g"are attached in a vertical relation the lower ends of the respectivevertical legs of the chair G. From the legs g f' at right angles and ina direction opposite to the su ')ports 57, extending in a horizontalrelation the seat 1/, and from the outer end of the seat y, rodsareextended in a vertical relation, which forms the back g of the chair.

In saloons of sea-going vessels the floor A and table are subjected to aracking movement, and to enable the chairs (fl G to vibrate and theoccupant to preserve as near as may be a vertical posit-ion inde e|nlentol' the movement of The Table the upright portions g of the supports 5 gare cut away and removed from the [front portion of the seat y, (seeliig. T3,) and in the upper ends of said portions are madetheperforations g. l'pon the outer side portions of the seat g, at anintta'mediate point between the front. and back portions, are rigidlyattached in a horizontal relation the pivots g, To which pivots arefitted the perforated ends of the supports g".

To the :front portion of the seat; is at:- tached a curved bar, g whichextends downwardly a short distance to a point nearly in a vertical linedrawn through the center of the seat. g", and upon the lower end isattzwhed rigidly a weight, g.

In the operation of the table The chairs (at G, which. are arrangedaround the table, are drawn out The proper distantai for the seating ofthe occupants and secured by a thumbscrew, f which extends through Theportion f of the dovetail portions of the guide 1 and impinges against 1he bar g. The foot portion (-5 of the lever (,J is then depressed towardthe floor, which carries The band b around the pulley I), and. theshaftl and table E, with The chairs (l, are given a combined rotarynmvement, which may be limited in degree by the action of the.ii'oot-levtn'f The occupants ot' the chair may be then served. from onestationary point near the toot-l ever.

It will be observed that when the vibrating chair is used the occupantmay adjust his position in relation to the table, the weight beingsulticient to retain the unoccupied chair in a constant verticalposition; or to assist in preserving the \(EHTlOill position of theoccupant the gravity of an increased weight may be utilized.

ll'aving tally described my invention,what I new claim as new, anddesire to secure by Letters Patent, is

1. The combinatitm, with a rotating table, of a vertical rotatingpower-shaft adapted to support and rotate said tal de, su sp en soryrods adjustably' attached to said table, and a seat connected with saidrods adapted to rotate in union with. said table, as described.

2. The combination, with a rotating Table ]T (l'\'ltl(tl with su'pn'rrting-gnidesonits under IO support and rotate said table, suspcnsoryrods ad j ustably attached to and beneath said table in said guides, aseat pivotally attached to said rods, and a, counterbalancing-weightattached to said seat, for the purpose described.
